Title: Ellipse scan converter
Inventor: ISHII HIROSHI
IPC: G06T11/20
Filed: 1991-06-27
Abstract: PURPOSE:To obtain a scan converter which can draw an ellipse in a high speed revolution with a small-scale circuit and software. CONSTITUTION:A parameter setting part 10 sets the parameters (longer and shorter diameters, center coordinates) of an unrevolved ellipse, the rotational angle, and the ellipse and straight line DDA(digital differential analyzing) initial values, etc. An elliptic circumference coordinate calculation part 12 turns the unrevolved ellipse into a raster with a DDA operation or applies the scan conversion to the ellipse based on the set value of the part 10. A 1st straight line coordinate calculation part 14 turns a 1st straight line whose slope is defined as the rotational angle of the ellipse into a raster with a DDA operation or applies the scan conversion to the straight line based on the set value of the part 10. A 2nd straight line coordinate calculation part 16 turns a 2nd straight line orthogonal to the 1st straight line into a raster with a DDA operation and applies the scan conversion to the 2nd straight line based on the set value of the part 10. The conditional DDA operations carried out by both parts 14 and 16 are controlled by a coordinate calculation control part 20.

Title: Internal clock generating circuit
Inventor: TANAKA KIICHI
IPC: G06F1/10
Filed: 1993-07-26
Abstract: PURPOSE:To prevent a transmission delay in an internal clock from giving effect on a timing of an output circuit by feeding back the output of an internal clock drive circuit driving a load to a PLL circuit so as to take synchronization with an external input clock. CONSTITUTION:An external input clock 1 is inputted to a PLL circuit 2 and an output 3 of the PLL circuit is inputted to an internal clock drive circuit 4. An internal clock drive output circuit 5 applies a clock to each section in a semiconductor integrated circuit to drive a load 6 parasitic in each section. An output 7 of the internal clock drive circuit driving the load is fed back to the PLL circuit 2 and inputted. The effect of the phase lag of the input clock 7 of an output circuit 8 due to an internal transmission delay is avoided by allowing the PLL circuit 2 to make the phases of the external input clock and the internal clock 7 match with each other.

Title: A/d converter for rf
Inventor: TAKEUCHI YASUTO
IPC: H03M3/02
Filed: 1989-07-14
Abstract: PURPOSE:To minimize the noise in the vicinity of a frequency in use with a low distortion and a wide dynamic range by applying an oversample type A/D converter, which is based on a DELTA-EPSILON modulator used as a band-pass filter for a high frequency signal, to an ultrasonic system. CONSTITUTION:A sampled analog signal having a center frequency f0 is inputted to a computing element 1. Since the output of a band pass filter (BPF) 12 is inputted to the computing element 1 also in a steady state, addition/subtraction is performed to execute the operation of signals having the same phase in accordance with the polarity of an input signal. Only a signal having the center frequency f0 out of the difference signal is integrated and passes through a BPF 11 and is encoded by a comparator 2. This encoded signal is integrated by the BPF 12 and is converted to an analog signal having the center frequency f0 and is operated as the sampled signal just preceding the input signal in accordance with its polarity to obtain the difference between signals having the same phase. The encoded signal of the output of the comparator 2 is converted to a digital signal by a decimation filter 5 and is outputted, and thus, the input analog signal is converted to the digital signal.

Abstract: PURPOSE:To easily and surely check recorded information in a short period by providing a check area where bits are arranged with a periodic pattern and comparing the Fourier transform spectrum image of the check area to check recorded information. CONSTITUTION:Parallel rays 4 are projected to a pattern 5 to be checked in the check area on an optical card to form the Fourier transform spectrum image of the pattern 5 on a space filter 8.
